Copper foundry. Image 3 of 3. Workers at a copper foundry using an electric hoist to hold a crucible of molten copper while using a cradle to pour the molten copper into moulds in a sand-filled barrel. The copper will set in the shape of the mould, a process known as casting. Copper is a chemical element and a metal, with a melting point of 1084 degrees Celsius. Copper is an easily worked metal that is used extensively in industry, in metal statues, and in alloys. Photographed in the UK. See images T810/256-258 for a sequence showing work in a copper foundry. See images T810/259 and T810/260 for close-ups of the moulds and the furnace, and T807/074 for the mould and the finished product.
